# to '../configure'.

# based on the values of the standard Make variables above.

# Where to put executables to be run by Emacs rather than the user.
# This path usually includes the Emacs version and configuration name,
# so that multiple configurations for multiple versions of Emacs may
# be installed at once.  This can be set with the --archlibdir option
# to '../configure'.
